I don't know what "be it in" means. In some situations in our lives, we can enjoy present and future benefits at the same time. For example, students who truly love learning get present benefits from the pleasure of discovering new ideas and future benefits from the ways in which those ideas will prepare them for their careers. In romantic relationships, some couples enjoy their time together and help each other grow and develop. Those who work at something they love — be it in business, medicine, or art — can progress in their career while enjoying the journey. However, not everything we do can provide us both present and future benefits. It is sometimes necessary to give up present benefits for future benefits. Studying for exams, saving for the future, or working long hours is often unpleasant but can help us to attain long-term happiness. — be it in business, medicine, or art — I don't know what "be it in" means. Please help me! Thanks!
