It has been proven that under convenient and easy terms, a mediocre human being does little to improve their living. Therefore, your character can never be matured in peace and quiet but only through experience of trial and suffering. Your worth is equal to your ambitions. When you follow closely the great achievers of our lives would not succeed in small things if they were not troubled with great ambitions.
If these great achievers where present, their personal advice would be, believe in your capabilities. With some basic skills, ambition and persistence then there is little limit to what you can achieve and by trying you can often surprise yourself.
Another important personal advice and key to self-improvement is the realization that success is not a particular destination. You do not have to stress yourself out trying to do too many great things in life. Just do what you do in the right manner and avoid doing being a jack of all trade. Winning is not a onetime thing. It is a habit. Doing little things of life in a great manner can be a great source of joy. It is by crossing small pebbles in your path that you find that you have crossed mountains.
No matter what hardships and perplexities you might be facing never lose faith. They say life is a good book, the further you read the more it begins to make sense.
