Leadership comes from
not "out there"
Who you are as a person has an effect on who you are as a leader. The way you. Understand and interact with the world, how chatty you are, how thoughtful you are....
The good news is this means anyone can lead, take a lead, learn to lead.... The way to learn how to lead and influence what is "out there" - the follows, the context, is my paying close attention to what is going on "in here".
There will be times as a leader when you will be visible. When people will be looking at you, to you. You may need to be tenacious, determined. You may need to compete to win.
If these things are Uncomfortable for you and to you, you have choices 1) run away from what is uncomfortable and make everything better/safer/ more comfortable.
2) face into the discomfort and accept the learning that comes
3) fake that you are fine. Hope no-one asks. Possibly fall over, possibly start to believe you are fine...
I guess what I'm trying to say is that you will need to be self supporting. I don't mean alone, I mean you have to build your own support networks and methods of sustaining. Yourself. Because it will get tough sometimes.
I have a notion about crunches for the soul - strengthening your core.
