Promotion by social media is a good thing.
Just don't do everything, every social internet platform.
It's ok if you're not (that) active on all of them.
Just take those ones you like and the ones that you think will work for you.
Sounds simple, but it's actually more effective than using all of them and think that will work.
Trying is not bad at all, but just try to learn from it (and move on if it's not working for you).
