That is a very straightforward questino brother sradin.
You should do anything and everything to please Allah. Start with the basics, like praying 5 times a day and become regular in it. I assure you, if you can do that, you will feel an urge inside you to know more about Islam. Gain knowledge and apply it in life. It is the most satisfying feeling towards your Lord. In other words try to apply Islam to all aspects of your life. When you do something, ask youself what does Islam say about this. Then research into the Hadith and Quran or ask some scholars for help.
Insha-Allah this is a simple guideline, but remember to make dua's regularly and ask Allah for forgiveness. Humble yourself.
