I have a few pointers, a recipe if you like:
Be happy in yourself - after all you worked hard at becoming what you aspire to this point. Remind yourself everyday that you DO MATTER!
Be grateful everyday - write it down in your Joy Journal, the smallest thing does count!
Reflect often on how you have grown and plot your next step with enthusiasm
Do not rely on people to pick you up everytime you are down. Do some of it yourself!
Phone friends and family often and tell them you love them. Not to recieve attention, rather to GIVE love and attention.
Take a walk outside and look at nature, sit on the grass, play with a pet.
If you find yourself being too negative, watch a funny movie or play or read a silly book. In no time your spirits will be lifted
Stay away - STAY AWAY from those that sow negativity, strife, jealousy, envy, gossip or seek to satisfy only themselves. They do not edify or uplift you - they have their own demons that you should not expose yourself to.
Any other ingredients you would like to add to this recipe????............ Lets do this!
