If you are frustrated with one thing and you think you cannot do it, don’t say that frustrations to other people. Don’t tell others that you cannot do something or this thing because the words are reflecting back on you. But before reflecting those words back to yourself, you are draining and your are imposing your negativity to them. Be positive even if you can’t find positive things in your present life. You know, what you are thinking right now, it will reflect in the future and you will pay for what you’ve said in the past. So, be positive even if you can’t find any justification to be positive in your present circumstances.
