In most things, when you want to push to the next level there is usually pain. Whether you are fighting for that promotion, debating the reasons why your marketing budget should be increased or educating your ignoramus colleagues on the process of branding; pain will be there waiting for you.
Don’t look for happiness there. Not during those moments. Unless, of course you like pain. When you are in pain to push to the next level, it’s the price you need to pay. You have to tell yourself that. It’s tough to find happiness when you are in pain, so don’t look for it there. Look for it after you have paid the price.
There is no need to torture yourself.
