Hey Markus, I fully agree with targets and regular reviews. I do this at the beginning of each year and find it so meaningful.
I do one extra step. For over 2 years now I have recorded every hour of every day. It motivates me not to waste individual hours (“I don’t want to record another hour of reddit”), let’s me review weekly and monthly progress, and helps provide SMART goals.
For two years I did this with a spreadsheet, but have been learning to code and have now crafted an MVP called www.everyhour.xyz
I would love for your feedback on it and the premise of recording hours. For me personally it has been transformative.
