Influence. Such a strong word. If you look back into your past and retrospect, you will find certain experiences that taught you or changed you, for the better or worse ofcourse. I remember my Parents being worried when I was in School, wanting to know who my friends were. Why? Because my character reflected my company to a great extent. And as I grew mature and understanding towards my surroundings I realised the Importance of having the Right People around me. No surprises that a point came where my Parents were more appreciative of my friends (ofcourse everyone has their share of flaws as well).
Coming to the point, that, you should choose your friends wisely. Especially the six people you spend the most time with. Would you want to be like someone who has bad habits, no ambition and disrespects life's offerings OR Would you want to be Positive, Passionate and Proud of the person you are? Think about it. I look at all the successful people today that I read about and I find one such characteristic common, and that is Knowing who your real Friends are? Do they uplift you or do they provoke you? Are they selfish or self-less? Are they friends? or mere Acquaintances?.
Small Things Make Big Differences. Everything beings with a Thought. Hope I could help lay down a platform to think from.
P.S.- Friendship is not being selfish. Its recognising who has his hand around you, and who doesnt.
Love All,...................Marry One ! (Haha)
To Friendship !
