Are you a procrastinator? Do you fail more often than you succeed? You have trouble making decisions and that's why you find it so hard to succeed. You can turn this around by developing the habit of making decisions quickly. Right now you think it's hard to make decisions. You find it hard to make decisions because you're focused on information rather than the facts, plus you don't have a specific plan for what you want and how you're going to get it.
Don't change your decisions once they're made. Once you make a decision only change your decision if the facts support that change. And even then change your mind slowly. The reason you change your mind so often and so easily is because you're reacting to fear not facts.
Make your decisions yourself. Reach and follow your decisions yourself based on the facts you've gathered, and the objectives you've set for success. When you include others in your decision making process you're only muddying the waters with misinformation, negativity, and jealousy. Develop confidence in your decision making capabilities through practice. There are few, if any decisions, that can't be undone. Start by making low risk decisions quickly and then sticking with them until you gain the confidence to make important decisions quickly.
When you need facts that you can only obtain through other people get them discreetly. Don't reveal your underlying reason for wanting the factual information. Keep your thoughts and ideas to yourself until you reach a decision and act on that decision.
It's far easier to make good decisions when you keep your eyes and ears open, and your mouth closed. There are opportunities around you every day, but you have to be looking and listening for them to find them. When you talk too much you can't be focused on finding these opportunities.
Never tell anyone about your plans. Others will know your plans when they see the results. If you want to avoid: ridicule for not following through on your plans, the likelihood that someone else will take your idea and directly compete with you, and having your thoughts and ideas cluttered with a bunch of ideas that detract from your focus; keep your plans to yourself until you've taken action.
