Don’t quit because something is hard in the short term if you are on the right path to your big goals.
Do quit when you are on the wrong path. Which can be any dead end path. If there is no growth, you can and should quit.
The right path will get hard. Don’t get confused or scared and quit then. Those aren’t the right reasons. This is the dip all successful projects have overcome.
