The problem with that is you never get to see reality in all its wonder! You go through life avoiding people who notice areas with room for improvement and judge anyone who is trying to help you as being "negative" (by your own "positive" standards of course). And while friends and others might support and inflate you, when the shit hits the fan, you never see it coming! And those negative people say, "I told you so."
I have found it is better not to judge and support everyone in their transition from negative to positive, because a lot of the time people just do not see themselves as being negative. It is part of societies conditioning and preprogramming they are breaking through and judging them only makes it all the more difficult. In a world-view of creating abundance and being positive and supportive, judging others is counterproductive.
I am all for supporting worthy projects and those in need and I also believe winning doesn't come from the predilection of special friends or from having "losers" on your way up because life has a habit of meeting up with them again on the way down, where they get to support us or judge us accordingly.
What you give to others is what life gives to you! Be it positive or negative (in our opinion). In truth, everything is a positive contribution if interpreted correctly.
Anyone has the right to be negative, I just don't want to mix with them and I think they do not want to be with me anyway because a always positive person is quite irritable for them. There is no judgment in that. It is just a choice to be with who you think will help better achieve what you want in life. Successful people all agree with that.
Thanks for the reply. That is a generalisation of course. I would not speak for all successful people or I would never learn anything new :)
