Having a strong sense of magnetism and charisma will help you no matter what you'd like to accomplish in life. Some people believe this is something that's genetic, or you either have it or you don't, but that's not true .
You can easily build up a strong sense of magnetism. It's all based on how you communicate with others, and how you carry yourself. Let's start with how you communicate with others.
When you talk to people, focus on them. Don't focus on how clever you are, or what you're going to say next, or that person over there that's better looking that the person you are speaking with. Focus one hundred percent on them, and what they are talking about.
Build up as much interest in them and their message. Don't fake it. Focus on them completely. Become as intrigued as you can. Clear your mind of all the clutter. (BTW, here' s a great way to do that:

When they're done talking, ask them open ended questions. Get them talking more about stuff they like talking about. When they do, show them somehow that they are special. Don't be fake. Be genuine. Find something about them that satisfies these two very important criteria:
1) It's got to be something that you really appreciate.
2) It's got to be something unique to them.
Then when you find it, let them know, in your own words, those above two points. When you start talking to somebody new, treat it like a treasure hunt. Look for those two items. When you find them, and let the person know you've found them, they will never, ever forget you.
You will create an army of people who think of you in very high terms. Now, most of them won't really do anything other than look at you with glowing eyes of appreciation. That's fine. But some of them might have connections that you need. Doors will open.
The second part is how you carry yourself. It's basically the same strategy. Except instead of focusing on the other person, just focus on the place you are.
When you walk into a room, for example, don't think about the past or worry about the future. Don't try and plan what you are going to do in that room. Just appreciate it. Appreciate yourself in that room. Truly believe, deep in your soul, that you wouldn't want to be any other place on Earth.
When you walk around with that attitude, and talk to people with that attitude, magic will happen.
