my life story:
ages 2-10: The Break-It Era. Hated school. Took apart every toy just to see how it worked. Learned more by breaking things than sitting in class. Somewhere in between, survived a major illness. Mum still says it was a miracle I made it.
ages 10-24: The Search Era. Moved cities. Joined a band. Fully convinced I was going to be a global drummer. Later pivoted to civil engineering and got the degree. Read widely. Showed up fully. Somehow kept ending up as a leader in almost every group I was part of.
ages 24-29: The Pivot Era. Tried to build a career in civil engineering. It didn't work out. Stumbled into tech and became a data engineer. Got married. Moved to the UK. Started a new life in a quiet city.
ages 29-36: The Dad Era. Best era so far. Had a daughter. Now I know every nursery rhyme by heart. Started my YouTube channel and newsletter. Started vibe coding and now pushing more PRs than Coca-Cola sells cans.
