Seafaring is not a Happy-Go-Lucky career. You must have a strong fighting spirit, courage, longer patience and be flexible all the time. If you are not as strong as that mentally and emotionally, then you're facing the difficulties while onboard at sea.
Life wasn't smooth everyday, you might said. Rough seas are just normal and can get over soon but homesickness is one that affects us undoubtedly. Problems from family at home is like a torture to us. That's why you need to learn how to separate those from your day to day routine at work.
You wish to leave behind you phone, fax, email and everything else that connects you to the world outside and just enjoy some quality time with yourself and your loved ones.
