Everyone wants to give up, so don't feel special. Life gets complicated and presents some tough challenges that sometimes we have to go alone. People don't understand what we are going through, and it can feel very isolating.
I am here to tell you that the obstacle you face is the real way. Think of your life and something you never thought you would overcome, and you overcame it. No one is encouraged 24/7. People get defeated and unmotivated, but you know what sets a winner apart? The ability to push through, the ability to still do something. However, you may not be 100%. You may be operating at 30%, but give yourself credit because you are committed to yourself and aren't breaking your promise.
Obstacles build character, and they build strength; everything you have been through that has challenged you gave you power. You literally float through the things that people trip over because of the challenges you have adapted and conquered.
Commit to yourself, and never break a self-commitment; even if you don't feel like tackling it, tackle it and get it done.
