The first tip is to be specific, be very clear about what you will be accomplishing.
Having a clear vision of what you want to accomplish will help you understand what you're going to need to get there.
Make sure your goal is measurable and that you have a method of tracking your progress from start to finish.
I use excel to measure my progress.
You don't need to complicate the process, the more simple the tracking method the more likely you will stick to it.
Your goal needs to be achievable.
The goal needs to be realistic and challenging.
Challenging yourself is what is going to make you grow.
If you set the goal to high, unreachable, frustration will follow along with self-doubt.
Your goal needs to be Relevant to who you are along your core values and passions.
Every part of your goal task should help you reach the ultimate outcome.
Your goal needs to have deadlines attached to them.
Having deadlines keeps you focused on your goal at all times and helps determine if adjustments needs to be done.
Make sure to break your goals down as projects and not having more than three projects for the year.
Again the goal needs to be realistic.
Setting goals should be an easy outline followed up with hard work.
The biggest secrete in being successful at goal setting is making sure the goal excites you.
If you are not passionate about what your setting out to do you will fail.
However, if you have a passion for what your goal is framed around you will be most likely see it through...
I hope this helps you to stop complicating the process.
