Your subconscious mind is very powerful; it can feed on thoughts of defeat or thoughts of success. What you decide to think about or dwell on will leave an impression on your mind that will affect everything you do day in and day out, every day of your life. The saying you are what you think is very true. What you dwell on will directly have an impact on your attitude positively or negatively.
If you trying out something new and along the line it gets difficult and frustrating to continue and then you give up frustrated with that thing, that frustration will have a negative impact on the rest of your activities. On the other hand if you continue through the difficulty working hard to find a solution, the impact of that victory will be seen throughout your activities. I am sure a lot of people can testify to this. Confidence stems from convincing yourself you can do it.
Don't waste your time, getting frustrated at things that are no big deal just because your subconscious mind sends you the wrong message. In actual fact there is no issue but because your mind keeps telling you, this is wrong, or you cannot make it, or you cannot do it, you bring stress upon yourself and this negatively affects your attitude. Do not let yourself get too caught up emotionally or negatively in something that really isn't necessary.
You are the master of your attitude and because of that, you can control your effectiveness, productivity, and results in your business or personal life. It is your choice to make. It may take some effort to train yourself to think a certain way, but it's worth it. That effort will translate to a better you.
Take charge of your life, think positive, not negative. Our attitudes and how we handle it is no joke but plays a major role in our lives. When you channel your thoughts to have a positive attitude, it will make you have better relationships and results in life.
