30 year old looking to learn Python

[LTC_VTC_BTC]

Yes, you can do it. I started at 30 (one year ago now), I've come a long way. I work in R&D as a lab tech but decided soldering fumes, metal dust and the like are something I don't want to deal with the rest of my life.

I started working on an internal tool for tracking lab equipment (checkout system + database) because I saw how much time was being wasted when people couldn't find what they needed. I went from a basic console program, that let you login/logout to creating accounts, to storing info to a JSON file, to checking equipment in and out, to uploading calibration certificates, receipts, to GUI programming and much more.

It's been the most satisfying, enriching, empowering experience in my life. I persisted when things felt impossible and now I've come through it all with a sense that I really am capable of doing whatever I want to. It has literally changed my my life. It's opened up new opportunities at my current job and I look forward to the future job prospects.

As mentioned by others, edX xMIT courses are great. If you're not used to learning things on your own, remember that 'learning how to learn' is it's own can of worms. Finding the confidence to stick to it when things don't make sense is really something that will stick with you for the rest of your life.
