As Melody Rose says "The important people in our lives leave imprints. They may stay or go in the physical realm, but they are always there in your heart, because they helped form your heart. There’s no getting over that."
How true is it..?! If you introspect your own life, you'll realise that just a handful people actually fall in the afore mentioned cadre but if you look at your friend's list in FB or for that matter any social networking site they would be anywhere close to 250+ on an average. Do you really know all of them in depths? So which statictics are true? I would say, instead of going by the statistics which is just a random count of numbers based on some absurd formula as a base; it is better to follow your gut instincts though at times serendipity just about manages to throw in the surprise bloomers which act as warm respite.
As you age, you'll come to realize that pleasing everyone is impossible but pissing everyone off is a piece of a cake. The expectations - fulfillment ratio has tilted off horrendously so much that its not worth a mention. Dealing with it detached and mechanically is the best way out..!!
Being a perfect human being in today's realm is a misnomer. I would say (after I've practiced it over years), adopt the realist approach; do what you're convinced of, spice it up with the values incultated in your system from your childhood, bellicose what needs to be revolted upon and just be YOU. The path is not laden with roses, you'll have to step out of your comfort zone, take the risks, struggle against the odds, attain your goals and realise your self worth for no one can do it for you. Its your LIFE and you're the author of your own book where you write your story in pen. Nothing can be erased from the past but you can only learn from them as experiences in life that help you surge ahead. Live every moment to the fullest for they'll form your memories when you look back at them.
There's always going to be bad stuff out there. But here's the amazing thing; light triumphs darkness, every time. You stick a candle into the dark, but you can't stick the dark into the light.
