Why I have many failures with blogging

Blogging is kind of a nice hobby for me, but I've failed so many times I can't even remember.
I think the reason is that it's like a marathon, stamina is the key.
It's not easy to commit to something for months (or years). Writing takes time and mental effort.
Life is challenging and giving up a blog might be the easiest option when we are overwhelmed with things to do.
