How about you just stop dipping your toe into the water and just jump all the way in. Add a picture and post that entire thought.
Freely follow people. Especially if they follow you add them to!
Easiest way to be successful here is to interact with people around you. But that is true for Life anyway.
Just because somebody hasn't introduced themselves that is just opened an opportunity for you to introduce yourself, and making connections here is greatly rewarded.
I am not the biggest person here but maybe you will take my words to heart and it will start a fire that will broaden your horizons.
Jump in. Just keep swimming! Minnows into whales!
Thank you @ganjafarmer for sharing your upbeat, full-speed-ahead, positive energy with me!
