We should think carefully before we do something. We should take precautions and do deep thinking. Then only we should decide to do something. Some people are impulsive by nature.
They do not think before doing a thing. They act rashly and then repent. We should do thorough calculations and also we should do a thorough survey. We should invest money in business only if we have experience in the business.
If we do not have the knowledge we can take guidance from experienced persons in business. We should make a thorough study before starting a business. Similarly, if we want to swim across a river, we should first see whether we can cross or not.
We should not start swimming without thinking about our experience and depth of the river. If we take action rashly or foolishly, it may ruin us.
