I made this change at 33. Went from a 12 year sales career into carpentry and its worked out very well for me but not quite as I expected.
I quit my well paid sales job and started labouring self employed on a site with a small building company. Whilst there I started investing in tools and making it very clear I wanted to learn. Spent the evenings doing wood work at home and teaching myself the basics with the help of some excellent you tube channels.
I spent a year at that company on £80 per day self employed and spent 4k savings on tool – was very tough
I then joined a larger company as a site chippy. Learning curve was very steep and I had to do a lot of practice/learning at home but am now confident with all 1st and 2nd fix including roofs… some plumbing etc. But it was tough as the pace of experienced chippy’s is very hard to keep up with when you’re new. Good tools and working in a tidy and organised way helps hugely.
I’m still at the same company now but have progressed to being the Operations Manager, leading a team of 15 trades people and as such very rarely do much tool work except at home… It was a great move for me
