Know that good things take a while to be enjoyed, so do not expect fast and magical success, put in your time and talent or ideas and be consistent. You cannot post many things in a day if your steem power is low. You need to do contest and post often so you can get rewarded and have a good steempower. You can use a 100 percent power up or 50sp and 50sbd. Do not try to compete with any one, it will only make you confused and make you stressed up, so work hard to be good for your self. Another way to get good up votes is by joining community support programs. As a new comer you can do a quick reading over acheivement 1 to 3 and get basic rules that are obligatory for you . Acheivement 2 is talking about your keys, if you misuse them or loose your account it cannot be retrieved. You need to keep your keys well, by sending them to your email, note pad, printing them etc . Check your wallet transaction daily to know if someone tempered with your account.
After you have logged into your account,and your wallet, sometimes you will have pup ups that ask you often to put your active key before carrying out any action, do not put it, tap on the (x) above it and reload your page. If it persist, contact your country representative or an old member you know so that you will not risk getting your account hacked. Acheivement 3 is about plagiarism. It sounds like a very big word. It means you should have nothing to do with copying and pasting if you cannot site a source. If you want post the same thing in more than one community, you have to use #tags so that your post will appear in the other groups. If you find something online do not fail to cite a source before posting or your post will be down voted , muted, and flag which will only tarnish your reputation on the platform because people will not take you serious and you will be stagnant.

The number next to your name is a reputation number which shows how you have been up voted and down voted, the more good Content you post, the more good reputation and followers you will have and the more down votes you get will not be good.

Do not see people happy or getting up votes and be discouraged. When you are consistent and discipline the curators will visit you.
