Keep smiling... those small worries and concerns will only be forgotten in a year's time. Be thankful for those small blessings that grace your life each day. Even when it seems things are falling apart, it takes the destruction of all the old to build up to the new.
Tell the people in your life that you love them. It does not matter how many people are in your life - love the ones you have. Be grateful they are placed in your atmosphere and seek out the knowledge and truths you are meant to learn from them... even if it is only to learn hot to be like them.
Invest in moments and memories, not things. It's not wrong to have a nice house, a nice car, or nice clothes as long as it is the memories made in that house and trips taken in that car and where you went with those you love that you hold most dear.
Above all, strive to just be yourself. Find out who you really are and be that person! Never stand on someone else's ground to be who they are - build your own hill to stand on and look around at the roots you have sown to be who you are.
Love yourself now. Not for who should be in ten years or ten pounds lighter. Not for the better job or better place ya'll be someday. Love you for who you are now, in each and every moment. And live with no regrets. Choices are yours.
