In the long run, developing patience requires a change in your attitude about life, but you can immediately make progress by learning to relax whenever you feel impatient. Take a few deep breaths and just try to clear your mind. Concentrate on breathing and you'll be able to get your bearings.
Being aware of your impatience also gives you a chance to learn from it and perhaps uncover a relationship or circumstance that is simply not healthy or constructive, and that you may have the power to change. Figure that out, and you can then think logically about the problem issue and decide whether or not your impatience is warranted or helpful. It usually isn't, but when it is you can then figure out ways to fix the root problem rather than simply feeling stressed about it.Always remember that you will eventually get what you want. (not really, and it requires maturity and patience to understand and accept that!)You have to learn to share the load.
Learning to be patient will make the clocks seem to move much faster than if you are constantly staring at it.
