Being a high achiever and staying focused is not easy. It takes time. The one advantage you have in terms of being successful is that 99% of people trying to achieve high goals are going to quit, so if you commit to staying focused, you're going to be in the 1% category with other extraordinary leaders.
Below, I've shared 3 ways to achieve any goal. The simpler you keep your strategy, the better off you'll be in achieving your goal.
Nothing incredible happens with inconsistent behavior. Direct daily action moving you closer to your goal is what's needed. You have to be willing to continue to fight and push through even when everyone else is running the opposite direction.
Keep Your Eye On the Prize
Always having that ever so important end goal in sight is key to success. When you're down, looking at the prize will bring you back up for sure. Take a picture of your prize, write down what you want to accomplish daily, and make that imprint stick in your head.
Have People that Push You
Surround yourself with people that don't buy your lies and keep you accountable. Great people want to hang around great people, so push yourself like never before to get to the next level of greatness. Peer groups are great for support.
As you've discovered from the 3 ways to achieve any goals shared above, it just comes down to you committing within, and taking daily action to move you closer to your ultimate goal. If you need help, ask for it, as many people most likely have achieved what you're looking to do and will be more than happy to share their insight with you.
