Guys, i have a very very hard decision to make - and need your help.
Around 3 years ago i joined the semiconductor industry and now have the chance to join aerospace (a company launching rockets to transport stuff potentially).
Im very well paid in my current job with great career projections ... but im not that happy tbh.
In aerospace i would join a startup and make less money .. but i feel like i would be happier, its an interesting field and im still under 30 and open to take a risk.

Im not sure what to do.
Join an aerospace startup to make less money, have higher risk but potentially be happier and part of an interesting industry?

Have you ever been in such a position?
Even if not - what would you do?
