Every time, people commensurate your background with your personality. Day by day, you develop with your outer environment so synergies with the environment are necessary. The only thing in you is your customs which deciphers the real you. The way in which you express yourself either your gestures or postures, everything matters.
Even the single word which flows from your mouth towards your audience
is relevant. I know that you will be thinking that you matter for yourself only. when you will achieve everything but how will you reduce your loneliness in a vacant environment. I emerged from the soil which even not a living being but still I’m alive. I died and then mingled in soil only. The earth is round as we know. The karma also revolves like the earth and the other things usually revolve in the same manner.
There is no anything which only matters. Everything matters but only with the time. Even the single technology which is not innovative yet will be important on one day.
