People with low self-confidence tend to be overwhelmed by big tasks and responsibilities.

it’s effective to take the larger or more complex tasks one step at a time. The idea is to look back at each milestone you’ve achieved and reaffirm to yourself that you can do the task at hand. Every big task is just a series of steps that you need to take. Don’t overwhelm yourself by looking at the big picture. Challenge yourself to take one step further, and once you’re done, look back and see what you’ve accomplished.
