I think the the need to post on multiple platforms when starting out comes from fear of rejection, it's like you put your time in many buckets, having hope something takes off - yourself thinks of it as risk management.
But what ends up happening is that neither of the platforms get enough time,,
but once something does take off it becomes very easy to abandon the other stuff,, as the risk is lost.
Thank you for the reminder,. I also have this tendency to want to do multiple platforms at many times, but I am gradually getting comfortable with just doing one thing - consistently.
