Stock Taking

Stock taking:

Things about me that should send me to Hell:
1. At times I lied.
2. I masturbate quite often.
3. I do not pray 5 times a day (sometimes 3, 2 or even none)
4. I look at women at times with lust
5. I watch porn when I can (and quite love it)
6. I indulge in frivolous and meaningless talk and chat
7. I keep dogs at home ( does this count? something like it makes the house unsuitable for prayer and that the Angels will not come into my house?)
8. I had pre-marital sex

Things that could help me from going to Hell:
1. I do pray when I can and tried do it 5 times a day.
2. I fast in the month of Ramadhan (full)
3. I never hurt anyone or any animals ( I am kind to animals)
4. I pay my Zakat
5. I donate to the poor when I can

You can't really itemise and then say with confidence that hey I got more pluses than minus and so I am not going to hell. The problem is actually because I had not tried to better my self, in practise and in knowledge about Islam, and THAT is the biggest sin (I think). How can I add value to my life as a Muslim when I don't even know what is valuable? I am too attached to this World and that is the problem.
