Esoterically speaking everything in this nature depends on either positive, negetive or neutral energies. If you want your surroundings to be happy and to be prosperous, you are attracting positive vibes, and on the contrary if you desire for their/its failure, you are attracting negetive vibes. Keeping this baseline, if you think positive, you are surrounded and attracted by positive energies around you, a common observation we find very often. Therefore, if you think it will go Right, high chances of its success, and if you think It will go Wrong, there are high chances it wont.
