Thanks! Thus the bottom line is that a rather skinny guy who wants to get bigger needs to have a diet extremly high in protein, minerals (e.g. zinc) and vitamins and carbohydrates and needs to focus on certain muscle groups excluding most of the other muscles till these recover from the last work out. Also, I should not go for a high number of repetitions until I can lift way more weight/have sufficient strength. Where the advice is a bit inconclusive is how many times you should work out a week and how many excersises. I've heard that too many excersises in one day greatly increase the probability of injuring yourself.
