Environment has a great influence on us. We tend to be like those with whom we spend most of our time.
You must be careful about who you spend your time with.
If your friends are drinkers, you are more likely to start drinking. If you associate with smokers, you are more likely to end up smoking.
If you spend most of your time with responsible people you will more likely be responsible.
