Your problems are so insignificant, they really don’t deserve the attention you give them.
If only homo sapiens were not so self-centered a species. It always takes a greater disaster to realise this.
There is a very good quote by Robert Fulgham, it tells you to realise the difference between a problem and an inconvenience. ( A very good description of it is found at Zenpencils, here)
I really like it, but would also like to add, that sometimes, you do have problems that may not be mere inconveniences. But they may not be the end of the world. Think about the various people struggling more than you, think about people in your own life who made sacrifices to get you where you are, think about the people who go through all this and never complain. Yes, you have problems, but so does everybody.
Make less of your problems and more of your successes. Prioritise happiness over discontentment.
