This resonates with me also. I've gotten into a nasty habit of always trying to do everything myself.

I recently launched a project for tracking crypto market data and suggesting trades. I went to Fiverr to see if I could get someone to design me a UI, and after going around one guy quoted me ~1.2k USD.

I decided that I could do it myself, and proceeded to spend multiple evenings working on it. I did learn something true, but it delayed the launch by weeks and if I factored my hourly rate in i probably "overpaid" several times over.

Getting past this "do it all" mentality is going to be one of my goals for the remainder of the year.
