Should you be a Flipper?

I say only be a flipper if you have no interest in the toys you are selling and your main objective is to make money. Initially when i first started collecting toys, i admit that i have this mentality of selling my toys at a higher price to make some profit. It is like a small business on its own, However, after years of collecting, i find that it is much fulfulling to actually help out people who have the same interest as you. Wouldnt it be so nice to sell someone at the price which you bought for? I mean i would really appreciate if someone sell me toys at cost. Also, over the years, I actually make friends who have the same interests as me in either boards or meet up. Personally, i dont feel good selling friends at a high price. You dont exploit your friends right?? If it is a total stranger, why not? Hahah.. But the point is, there are too much to gain from not flipping and helping fellow collectors. And you will definitely not get any name calling. To flip or not, you decide. What is your thoughts?
