Assalamo Alikom wa rahmato Allah wa barakato
When someone thinks about Islam just being rules, rules for the "hell of it", that's why people go astray, I think.
We have to understand that when Allah The Almighty give us a guidance and advise for our own good that's what we call a rule.
People don't like (or don't feel) when they are told to stop something they are "enjoying". For intance, when people fornicate, and you tell them to stop, believe me, they'll hate it! But when they realise that Allah wants to protect them from diseases, being hurt, being used, unwanted pregancies, low estime, disrespect, etc,etc, they will probably start appreciating and "feelling" right about such a "rule".
I think you have to know what really is behind of each rule. Allah has never said something to give us a hard time or just to bother us or make our existence more difficult. SubhanaAllah He is The Most Merciful and Kind and He wants a good life for us. It's just us that most of the time don't get it!!
If you haven't been a very practicing muslim (I'm just assuming) is also difficult to start feelling in your heart all the so called 'rules' just overnight. It is a process, it's a give and take thing. As you get closer to Allah The Almighty, it'll be easier for you to understand it, enshaAllah.
Just remember that we all have sometimes felt to do something wrong like punching someone, for instance. I can assure you that none of us has really felt in the heart to stop, forgive and kiss that person at that precise moment of anger, but deeeep inside we knew that it would've been wrong to go ahead with the punch, and we did stop even going against our own feelings at the time.
We cannot base our believes and faith on our feelings most of the time. One day we feel like praying, next day we don't; one day we feel like loving, next day we hate, sometimes we feel ill, sad, or lazy, sometimes we don't. As you see, we fluctuate all the time, we were created weak, therefore Allah has set boundaries and advises for us to keep sane!!
Can you imagine Allah telling us: pray just whe you feel in your heart like praying, or perhaps help the people in need just when you are convinced of it, or fast when you feel it ?? Can you just imagine? Nobody will do it!!
Allah knows best.
