When we choose not to learn and not listen to others in our path, then we prolong or may never even achieve our dream. God brings people in and out of our lives just as seasons come and go.

We should be open minded enough to discern, with the help of the Holy Spirit, whether this person is speaking into our life that will lead us to our dream or cause a distraction therefore loosing focus.
Focus is key. Put a crosshair on your goal and aim to get there. The journey is sometimes long but the time invested now will bring harvest to your future. Basically, it is wise to invest in your future today.
