The number beside your name is your "REPUTATION SCORE." Everyone on Steemit starts with a score of 25. Based on your number of posts, your comments and replies, and your upvotes, your score will increase (or maybe decrease).

As for "a lot of income," in fact, I have not earned a lot of income over my 2.5 months. However, I did "Power Up," which basically means to "buy Steem Power" (instead of just earning it).
As implied above, there are 2 ways to get additional Steem Power (SP). One is to earn SP, by posting, commenting, replying, and upvoting. The other way is simply to buy SP.
Since I plan to be active on Steemit for a long time, I decided it was best to Power Up by buying Steem Power. That's where most of my current Steem, SBD, and SP came from.
You’re really awesome. Thank you for explaining in detail for me. I understand more now and I hope other steem users who read this will also learn from it.
I’m also planing to stay longer here in steem same as you. So maybe I will start doing the same thing as you gaining more reputation point and buying steem power in the near future.
I hope we could get big here in steem.
Glad to help. And I'm glad we have this great platform that allows and encourages this help.
Keep plugging away ...
