It’s going to be hard, but hard does not mean impossible.
Nothing great can ever be achieved without enthusiasm. No journey can be walked without having a struggle. You have to climb the steep mountain to reach your goal. You may feel like quitting if it’s not working at that time, but remember your journey can be difficult full of hurdles but it is not impossible to reach your destination. It may take time to reach your destination but you will be there surely one day. So do not lose hope. Keep working hard to achieve what you want. Jour journey will be the reward for your achievement.
