We explored the impact of admiration of others regarding their morality, positive attitude, and skills on the fatigue of social media users through the mediators of social media loneliness and social media anxiety. We collected data for analysis from 688 social media users through an
online survey. The results show that admiration for morality relieved social media fatigue through the mediator of social media loneliness, and admiration for positive attitude relieved social media fatigue through the mediators of both social media loneliness and social media anxiety. However,
admiration for skill aggravated social media anxiety and, further, led to social media fatigue. Admiration for morality and for positive attitude could directly relieve social media fatigue, but admiration for skill led to social media fatigue only when it was transformed into social media
anxiety. Our findings have implications for ways to relieve social media fatigue.

The Covid-19 pandemic which has spread in various countries has a severe impact on all sectors in every country, especially the economic and tourism sectors. One of which is Singapore, which has closed access to foreign tourism with a lockdown policy and has progressively implemented a series of steps to reduce the risk of a wider spread of the COVID-19 pandemic in the community. Singapore has managed to maintain sustainable tourism over the years. Several tourist attractions in Singapore have resumed operations after being closed for several months. Indonesia was the market for the first largest source of income from tourism for Singapore for five consecutive years in 2016. This study aims to determine the perception of Indonesian travelers to return to tourism after the Singapore government reopened tourism to foreign countries. The research method used is quantitative, the sampling technique uses non-probability sampling and a sample of 285 respondents is obtained. The analytical tool used Path analysis and the hypothesis uses a significance test using the Partial Least Square Structural Equation Model (PLS SEM). The results of this study indicate that destination attractiveness, tourist motivation, accessibility, and risk perception can directly revisit the intention of Indonesian tourists to travel in Singapore. Then, destination attractiveness and tourist motivation can affect the revisit intention of Indonesian tourists to travel back to Singapore after the Covid-19 outbreak.
