It happened that I switched jobs at the end of August. Upon hearing that this was about to happen, a friend pinged me and asked whether he could hire my services for "one to two hours per week". I rejected the offer. I specifically told my friend that "one hour per week is a trap":
A week is 168 hours. You sleep 56 of them, so let’s say that you have to give 1 hour out of 112. To be more precise, 1 hour out of 72 you can spare. Surely you can allow yourself 1 hour of a side-gig, right? But then it is Monday. And you start your working day, and "oh, I’ll deal with this tomorrow" and this goes on until Friday and you say, "I’ll do it Saturday morning before the other chores". And you squeeze that hour somewhat grudgingly, between Saturday and Sunday night.
If I’m wrong, why are then all those Udemy / whatever vocational courses you’ve purchased unfinished? Did interest wane down on all of them right after the first couple of hours?
So say no to "one hour per week engagements". You’re setting up yourself for frustration and failure.
As for me, I’ve arranged for virtual coffee with my friend once per month to discuss his vision and progress. Because everyone needs someone to talk to.
