First of all, I appreciate the time you took to write this text.
Neither being shy nor having terrible mistakes justify not participating in this session.
I am pleased that you have enough enthusiasm and courage to write an English text by yourself. Unfortunately you have some mistakes in your text; therefore please let me correct them.
sorry because I answer (You are answering a question. Or you answered it. Because you are willing to answer it now and it is temporary, you have to use present continuous.) this Q first :
anyone who has experience (it is better to add an specific experience, not in general. E.g. experience of modern life) can answer this question but no one can prove it because they just say their behavior(insights or suggestions or their personal ideas)
you know it is not a scientific Q therefore no one can support (their) idea very strong(strongly, try to use adverbs, in this case, predominantly is more meaningful)
but my idea is that both have(having) goal and good luck is too(so- too has negative sense) important. we have 2 goal(s):the short-term goal and the long term-goal and usually the short term is in a way of long term
have(ing) a great plan can help(us) to achieve dream and goal.it is necessary to work hard.if you take it easy you are going(will is better, when you use “going to”, you mean it has been decided, for prediction it is better to use will, however “going to” is not wrong) to lose in this big game but if you (already) have had experience like have(having) a problem or have(ing) not enough benefit never never embarrassed (? I can’t get it. Could you write in Pesian?).losing and doubt are steps of victory.i can not say everything is goal and work because we believe that good luck can change everything like people who do not have anything and have low IQ but just for a good luck know(?) they have everything you think
.at last i want to say (believe it or not) self-confidence is the most important thing in life
