How to be serious towards taking actions in life
It's a tricky one and depends on what kind of person you are.
A lot of what stops people taking action is the feeling of whether or not they are making the right decision especially with life changing decisions. So first figure out what it is that you want above all else, there is no limit, try not to think about all the limitations initially. You need to believe that what you want is possible even if you don't know how at the time.
Then what you need to do is mentally and emotionally commit to what you want. Once you have made that commitment your mind will look for ways and identify opportunities to make your commitment a reality.
None of this will work unless you take positive action steps to achieving your goals. Break your end game up and figure out how you are going to get there. You are not a genie and you cannot control the world, things will change, so you need to learn how to adapt.
Action plans are good to gain clarity and perspective, remember things change. Always keep your end game in check, be present and focus on succeeding in the now.
