Over the course of my 24 years in technology I've felt like this many times. It feels like you hit the valley floor and you don't see the mountains on the other side.

After the big Y2K push. I was making a ton of money and had lots of money in the bank, but was working on uninspiring projects that just felt like I was going to work just to pay the rent. I left that company and moved thru several positions with different startups. Some had passion and some where just created to steal money from investors (literally).

Whatever you're feeling now, will pass if you are focused on some sort of goal.

Take some time and think about what you really enjoy about technology, what you'd like to learn and where you'd like to go. Then create some kind of outline of how to get there. It will help you the next time you feel this way.

Good luck!
