I decided to start this post with a quote. Well, not just a quote, but the best quote I´ve read in a long time. Everyone - and I mean everyone - should reflect over what you make of your life, because you are the only one who knows what you truly want and what´s best for you. If you won´t take control over your life, no one else will. There might be someone who will try, but they often have their own motives and they won´t take into account what´s best for you. The person who have the best qualifications and capabilities to control your life, is yourself. Then do it - take control.
There will always be factors that will partly control your life for you, like your responsibilities and your duties. You can´t only fill inn the rest of your time with what you want, you can also choose how to meet your situations. If you go to work with a huge smile on your face, determined to get a lot done and also see if you can get in some flirting with that cute, new colleague, your day will turn out a lot different than if you went to work just to get time passing faster, and avoiding that colleague because "(s)he probably finds you dull and unattractive anyway".
Being positive and ready to seize the day, everyday, can´t be easy, and I´m not asking you to be that "exemplary" - I am definitely not like that - but think about it, what can you do today to make your day better? What did you do yesterday that made your day worse than it had to be? What can you do today, for tomorrow to look brighter? Three questions. It´s up to you to find the answers.
