It's important to take frequent breaks during your revision session. The brain is a muscle (not factually correct) that gets tired like any other muscles (do hearts get tired?). In order for a break to be effective, you must fully remove yourself from your working mindset. Dig a hole in the garden or annoy your sister a bit. Just keep the line between work and play clearly defined.
Life has to be more than just being about what's absolutely necessary, we have a network around us which needs an element of input and equality in order to thrive. What is a life without wonderful friendships and relationships? All contributing to adding layers and enriching our experience along whatever direction we pursue, it can be a lonely path when selfishness prevails, even if it is only because you initially just wanted to cope and not let anyone down.
Making time for yourself and expressing self-love as a mother, daughter, sister or auntie is so very important and something that we all need to practise as time allows. Just a snippet in the day or week to yourself can make all the difference to your all round happiness and your body and mind will only thank you for it later.

Lack of job opportunities has also driven entrepreneurial change and so made starting up your own business a much more attractive alternative.
