Yep, another 34 year old here. Welcome to the board zxxxt.
My plan is to retire in about 10-15 years. While I could probably pull the plug earlier, I definitely want to have enough discretionary income in retirement to be able to do plenty of interesting things that often cost money (like traveling...). But I have noticed something interesting in the past few years. When I was working full time I spent a lot of money on "stuff" because it was a quick and easy way to make me feel "happy". Now that I reduced my workload and I have more time for myself, I don't feel the need to spend so much money to feel happy. Don't know why, but these days I pretty much have to kick myself to go shopping...
