When surrounded by challenges, sometimes we all need a little extra nurturing, and that gentleness can come from loved ones, or just from ourselves. Also, enjoying the hot chocolate and the coffee, enjoying the cold drink and the ice cream, enjoying the brisk walk and the gym, enjoying the picnic and the party, enjoying the holiday - these are all things that help us replenish our energy and remain motivated to some extent when we've had a rough day.
But remember that to remain constantly motivated you need to also take a look at the non-physical dimension of thoughts and feelings. Physical treatments, therapies and relaxation strategies will help you but they cannot change the way you think. Your thinking is the cause. And behind your thoughts, your beliefs are a deeper cause.
We need to pay much more attention to our thoughts and feelings, learn to manage them, learn to fill them with peace and calm, and then our personality will change for the better, as we restore our mental and then physical well-being and learn to remain motivated and fearless amidst challenges.
Remember no one else creates our thoughts and feelings, and they don't just happen, though it feels that way sometimes. When you learn to identify and assess the quality of your thoughts and feelings, you can begin to choose the ones you know are positive and that in turn keeps you motivated.
Also, remember there's virtually always something positive that can be found in the challenges we face. Bear in mind that the period of challenge is short and you will soon overcome the challenge. On a lighter note, spend a little time each day thinking of all the things you are looking forward to doing once you are free from these exams that life has to offer - though don't daydream for hours about this! Also, when you long for life without difficulties and challenges and you want to keep yourself motivated when faced with them, remind yourself that oaks grow strong in contrary winds and diamonds are made under pressure. Challenges are not here to stay and while they are there, they bring about self empowerment.
