Your goals are hard to achieve if you allow yourself to get distracted. Let friends and family know your schedule and when you are available. You need to commit to yourself, and your passion to achieve your goals.
Take a break from your usual day to day and break out some of your creativity to create a vision board of what you want. It is helpful to see your goals in a visual representation. If you can see it, you can achieve it.
To set better goals for yourself, you need to know who you are. Take some time to figure out who you are, what you are good at and what you are not good at. How can you use that to help you set goals that you can achieve.
