    14 Why Consistency Doesn’t Work for ADHD (Persistence Does)

    If you’ve ever felt like you’re failing because you can’t stay consistent, this episode will change how you understand your brain. In this episode of ADHD Late to Know, I explore why traditional productivity advice often fails ADHD and AuDHD adults — and why persistence, not consistency, is the real path to progress. We dive into the neuroscience behind commitment, executive function, and attention - including why shame spirals, rejection sensitivity, and autistic inertia can make starting or returning to tasks feel impossible. You’ll also learn practical strategies for working with your neurodivergent brain rather than against it, including: • The Minimum Version Rule for hard days • How curiosity enables persistence with ADHD • Why persistence reduces shame and burnout • How to return to tasks after setbacks without all-or-nothing thinking If you’re late diagnosed with ADHD or AuDHD, this episode will help you reframe productivity, self-compassion, and what real progress looks like.

    12 ADHD & Autism Tax: The Hidden Cost on Health, Energy & Money

    Being neurodivergent comes with hidden costs — not just emotionally, but to our energy, health, finances, and long-term wellbeing. In this episode of ADHD Late to Know, I explore the tax of ADHD and Autism from an AuDHD adult perspective: how chronic stress, masking, nervous system overload, and lack of support quietly add up — and what we can do to protect ourselves. We talk about: Research linking ADHD and autism to poorer health outcomes and reduced life expectancyWhy burnout and exhaustion aren’t personal failures — they’re systemicThe financial tax of neurodivergence: impulse spending, forgotten subscriptions, convenience costsProtecting energy through pacing, boundaries, and safer socialisingIntentional thinking about your future self — wanting to feel nourished, rested, and steadily working toward what mattersPractical systems that lower the tax without shame or perfectionism This episode is about awareness, self-advocacy, and building a life that costs you less to live — and gives you more back. For adults with ADHD, autism, AuDHD — and those who want to understand and support them better.

    11 ADHD Coaching... So Life Isn't Always on Hard Mode

    In this episode of ADHD Late to Know, Holly is joined by Ria from Ri-Align Coaching, an ADHD-specialist coach supporting ambitious, high-achieving adults who feel overwhelmed, burnt out, or stuck despite their capability. Ria shares her powerful late-diagnosis journey — from years of feeling like life was on “hard mode” to finding clarity through ADHD understanding and building a career aligned with her strengths. Together, Holly and Ria explore what late-identified ADHD and AuDHD can really look like in adulthood, including burnout, emotional dysregulation, masking, people-pleasing, rejection sensitive dysphoria (RSD), and self-doubt. This conversation gently reframes ADHD away from constant self-fixing and towards self-trust, nervous system awareness, and working with your brain instead of against it. Ria also explains how ADHD-informed coaching helps clients rediscover their strengths, rebuild confidence, and move forward in a more sustainable way — especially when traditional routes haven’t worked. The episode also covers: Why so many ADHD adults feel “capable but exhausted”The impact of lifelong micro-criticisms and maskingHow strengths can become saboteurs without boundariesThe role of coaching in late diagnosis and identity rebuildingADHD support at work, reasonable adjustments, and Access to WorkWhy chemistry and safety matter so much in coaching relationshipsThe “penny-drop” moments that change everything for Ria’s clients If you’re late to understanding your ADHD, questioning your neurodivergence, or learning how to build a life you feel proud of, this episode will help you feel seen, validated, and less alone. 🔗 Find Ria: Website: ri-align.co.uk Instagram: @rialigncoaching
