Why do so many of us fear challenges, and what actually happens when we push ourselves to do something new? I recently joined BBC Radio One’s Life Hacks with Lauren Layfield and Shanequa Paris to explore this very question, and here’s what we uncovered.
Our brains are wired for safety. The amygdala – the part that processes fear – pushes us to avoid risk. While that helps protect us from genuine danger, it can also make us underestimate our own abilities. Taking on a challenge helps rewire the brain by creating new neural pathways. Every time we face discomfort and survive it, we build confidence, resilience and motivation.
Our self-doubt often comes from early experiences. If you were criticised or protected from failure as a child, you may fear mistakes or struggle to trust your ability. Knowing this helps you shift perspective. You can’t change the past, but you can choose how you respond to fear today.
Some people thrive with external accountability – telling others, joining a group, or being coached. Others are internally motivated. The key is to know what works for you and build your challenge around that.
Support isn’t just about cheering someone on. It’s about: - Helping them adapt when things go wrong - Reminding them of their reasons for starting - Celebrating their effort, not just the outcome - Being a safe space where failure isn’t feared
Taking on a challenge isn’t about being perfect, it’s about discovering what you’re capable of. Growth happens in the process, not just the results. So whether it’s running a marathon, performing on stage, asking for what you’re worth at work, or just trying something new, push the edge of your comfort zone. You might just surprise yourself.
