Grasp that it’s YOUR life, and no-one else’s life.
Decide to “live on purpose”.
Recognise that achievement has a price tag attached to it – and decide you’ll pay that price.
Work on constantly maintaining your focus.
Chose a skill or a field and become competent, or an expert, in that area.
Find other people who will hold you to your goals – and will believe in, and encourage you, to strive to reach your dreams.
Consciously notice the progress you are making, and remind yourself “it’s worth it” as you’re further on the path.
