Make friends. Networking is the largest foundation on which to build an entrepreneurial enterprise.
Have a thick skin. Don't get discouraged when older users rebuff your attempts for business or leisure, there's a stigma about "newfags" being blithering children and undeserving of respect. Remember that it's not about you, that's just unfortunately the community attitude; don't take things personally. The best businessmen separate emotion from work.
Buckle in. It won't happen today, tomorrow, or next month. You need to build your reputation organically, and that requires proof that you're trusted, and proof requires many many many small transactions. No transaction is too small or beneath you.
Be safe. Don't be desperate for transactions. If your gut tells you it's unsafe, stop and reevaluate. Ask for an MM or staff, take screenshots of every process, cover your own ass. No one else will, you need to keep YOU safe.
I understand when you're asking "how do I become successful, where do I start" that you're wanting someone to say "PM this user, they hook people up with business start ups." There's no such thing. If you want it, YOU need to get it. Sure, there are key people, suppliers, low price bulk salesmen, etc, that could help you get a better start. But no market giant is going to disclose their tricks and tips when it could mean increasing their competition in the market. That's where networking comes in, and why I'm emphasizing it to you. YOU find these people through networks, they don't find you and they're definitely not given to you.
And if you're wondering why you should take advice from someone with DNT, you don't have to. Listen or no! That's the beauty of free will. But if it rests your fears, my DNT is self requested because I've been hacked before and they tried to trade. This is just my deterrence because I'm no longer active in the slightest in the market.
