I'm in my mid twenties, and I'm in a safe, comfortable job as a Software Developer. The work environment is great, I'm well paid, the benefits are good. I enjoy my job.

Some friends passed my name on to some guys starting a new company. I had some informal chats with them and they liked me. They've asked me to joint their start-up as tech lead, designing and building their product from scratch. They're fully funded, and they know what they're doing.

Taking the job would require giving up my safe, enjoyable, relaxed job for a risky, stressful, hard one, albeit with the potential to be really great in future.

Should I take the job?
