The things which make me regret

In our life there are many things which we do, knowingly or unknowingly, for which we regret later in the life. But sometimes we regret on those things for which we have not done in our life. I feel there is only one life to live and the days which have gone by will never come back to us in this life, so we should enjoy each & every moent of the life to the fullest. In our every phase of life there are many things to do, and which should be done in that phase of life only. In my life also there are many such things happened which I haven't done during that phase of my life which have passed away. One of the thing is that I haven't done is I am a very shy person and have not approached or talked to any girl of my own, and so never have a girlfriend in my life for which I regret the most. Many of my friends who have one or more than one girlfriends always make fun of me by talking of their girlfriends and their relationships. I sometimes feel very frustated by their words, but hold my emotions by just diverting of the topic.

Sometimes I think that doing these type of affairs are a very challenging and interesting thing but sometimes it feel like very boring or time consuming, which affect our career(or it is just a way in which I could console myself).

But seriously when I think that why I don't have a girlfriend, then I have the answer that I have nothing that a girl wants in his boyfriend, i.e. good looks, personality, and above all, money to impress someone.
Although I regret it very much, but now, in my present phase of my life I barely have time to impress any girl to be my girlfriend, as I am now serious with my studies and career, and later on think of any girl after achieving any goals, as I now don't want to regret for anything else in my life.
